Answer: 5.39 hours
Step-by-step explanation:
For Jill:
Number of hours used = 8.4 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/8.4 = 4.7619
For Maria:
Number of hours used = 15 hours
Number of bushels of apples picked = 40
Number of bushels of apples picked per hour will be: = 40/15 = 2.6667
We then add the number of bushels of apples picked per hour for both of them together. This will be:
= 4.7619 + 2.6667
= 7.4286
If they worked together, the hours they'll take to pick 40 bushel of apples will be:
= 40/7.4286
= 5.39 hours
